Gung Ye, who had risen under the warlord Yanggil and taken Gangwon, Gyeonggi and Hwanghae, founded Later Goguryeo at Songak in 901.
Hong Yu, Bae Hyeon-gyeong, Sin Sung-gyeom and Bok Ji-gyeom overthrew Gung Ye and raised Wang Geon to the throne; he named the state Goryeo with the era name Cheonsu.
Merchants from Song, the Khitans, the Jurchens, Japan and even Arabia came to Byeongnando at the mouth of the Yeseong River, carrying the name "Corea" to the West.
When the retired chief minister Choe Chung opened his Nine-Course Academy, twelve private schools flourished; as state schools declined, later kings revived them.
Yi Ja-gyeom, King Injong’s maternal grandfather and father-in-law, burned the palace with Cheok Jun-gyeong and held the king captive; Injong won Cheok over and removed Yi.
Generals including Jeong Jung-bu, Yi Ui-bang and Yi Go, long slighted by civil officials, struck at Bohyeonwon, killing civil officials and deposing King Uijong; military regimes ruled for the next century.
Manjeok, a slave of Choe Chung-heon, gathered slaves in Gaegyeong to plot their emancipation and seizure of power, but was betrayed.
Having made peace with the Mongols, Goryeo moved its capital back from Ganghwa to Gaegyeong once the military regime fell, ending a century of military rule and beginning the period of Yuan domination.
A Yuan-influenced ten-story marble pagoda was erected at Gyeongcheonsa in Gaepung; it inspired the Wongaksa pagoda of early Joseon.
The Red Turbans, Han Chinese rebels against the late Yuan, invaded Goryeo twice; in the second invasion Gaegyeong fell and King Gongmin fled to Bokju (Andong).
Twin tombs of King Gongmin and Princess Noguk. Gongmin himself built his queen’s tomb, and its zodiac retaining stones and civil and military statues became the model for Joseon royal tombs.
Jeong Mong-ju, leader of the moderate scholar-officials who defended Goryeo against a change of dynasty, was killed at Seonjuk Bridge in Gaegyeong by Yi Bang-won’s men; three months later Yi Seong-gye took the throne.
Yi Seong-gye overthrew Goryeo and founded Joseon, moving the capital to Hanyang in 1394.
In late Joseon rice transplanting spread nationwide, allowing rice–barley double cropping and large-scale farming; farmers grew cash crops such as ginseng and tobacco, and periodic markets grew to over a thousand.
After more than two years of talks, the armistice was signed at Panmunjom, fixing the Military Demarcation Line and the Demilitarized Zone.
After the June 15 Declaration, an industrial zone combining southern capital and technology with northern land and labour was built at Kaesong.
